Walkthrough
Objective 1: Meet with the FIB
- Briefing: The mission starts with Michael and Trevor meeting Dave Norton and Steve Haines. During the cutscene, they are informed about the existence of a secret chemical weapon being stored in a government facility offshore.
- Dialogue: The dialogue provides background on the operation, emphasizing the FIB’s need for deniability and Michael’s hesitancy to continue working with them.
Objective 2: Infiltrate the Facility
- Underwater Infiltration: Players must pilot a dinghy to the drop-off point, where they don diving gear. Michael and Trevor then dive underwater to approach the facility. Use the sonar map to avoid detection by patrol boats.
- Breaching the Facility: Upon reaching the facility, players will need to use cutting tools to enter through an underwater hatch. Time is of the essence, as oxygen levels are limited.
Objective 3: Secure the Chemical Weapon
- Stealth Takedown: Once inside the facility, players must move quietly to avoid triggering alarms. Use silenced Weapons to neutralize guards and scientists as Michael retrieves the chemical weapon.
- Complications: After retrieving the weapon, Merryweather Security becomes alerted, leading to a firefight as players try to escape the facility. Manage ammo and use cover effectively to survive the onslaught.
Objective 4: Escape and Evade Pursuers
- Get to the Boat: After exiting the facility, players will board the dinghy again, but Merryweather helicopters and patrol boats will begin their pursuit. Use the mounted gun on the dinghy to fend off attackers.
- Drive to Safety: Navigate through the ocean while evading gunfire and pursuing boats. Taking alternate routes or switching Vehicles can help throw off the pursuers.
Mission Conclusion
